Alexander Roslin works almost entirely in the lower half of the value scale, privileging depth over brilliance. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #C3A781 - appears at just 5.1%, deployed as a precision accent against the quieter ground. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Alexander Roslin's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
